Although in Fig. 5 exemplary arrangement, obstruct or reflecting material 830/820 has been described and illustrated for and ink Separately apply, but it is to be understood that in alternative arrangement, ink can include barrier or reflecting material.

It is understood that transparency processing 850 can refer to the processing of the object after object 450 is formed.

It is understood that transparency processing can put on layering object, formed by different device-for example using Such as the system described in other patent applications of same applicant.

The final color of object is limited by the reasonable processing to each layer of object.Ink and/or barrier and/or Reflecting material can be applied on each layer of part.After object is manufactured, subsequent treatment can be carried out to object to carry For final color.

Indeed, it is possible to think that ink 240 can apply in the first direction relative to dielectric layer.For example, in a first direction Ink apply can effectively include ink is ejected into the plane of dielectric layer upper surface.Ink can further relative to Dielectric layer applies in second direction, that is, is applied to cut edge 410, and the ink is at shape cutting across the laterally horizontal of dielectric layer Section applies.As further described above, the quantity of ink in any part application of dielectric layer can be controlled so that be applied to medium Ink in a part for layer can be applied to surface or penetrate the depth of the layer of specific location.

Similarly, as pointed by barrier material 820 or reflecting material 830, it can apply and carry out limited boundary layer BL 865.For example, if a layer defines intermediate layer, boundary layer 865 can be the band for the lateral cross part for limiting dielectric layer. If for example, a layer defines the outer layer of object, boundary layer can also be the layer parallel with the principal plane of dielectric layer or surface. Any dielectric layer of object may include shape cutting outwardly and inwardly, and reflection 820 or 830 materials of barrier can also be applied to example It is taking for constant interval or depth such as with outside or inside shape cutting.

Fairshaped one side print procedure is related to an extra subsequent processing steps, makes paper translucent, and obtains complete Color 3D models.The opacity of paper is due to light scattering excessive caused by the refractive index between its main component mismatches.It is dry The hole and cavity of paper are filled with the air that refractive index is 1.Hole wall is made up of cellulose, and cellulose is transparent in itself, but has There is about 1.55 refractive index.This mismatch can cause the increase of scattering events, because individually the path of photon becomes no order Sequence.When using index matching liquid, the medium of hole is replaced by has the liquid closer to cellulose refractive index than air Body.Which reduce the track of photon, and then reduce the scattering properties of paper.

In exemplary arrangement, transparency processing material 850 can include index-matching material, and it can include glycerine Three ester groups oil, such as dryness, edible, nut, citrus, medicinal oil.Synthetic polymer sill such as acrylic compounds and polyurethane It can be used as transforming agent.Such material advantageously relatively low cost, it is environmentally friendly, it is safe to use and with as close possible to Cellulose（It is 1.55 in 592nm）Refractive index.

In another exemplary arrangement, a kind of processing 3D objects are so that one or more layers the selected part at least portion of object Divide transparent method, the 3D objects include multiple dielectric layers of paper material, and methods described includes：Transparency is handled into material Material is applied at least in selected part of object, and transparency processing material is configured as penetrating a dielectric layer or multiple dielectric layers Desired depth, wherein with transparency processing material be absorbed into dielectric layer, make the dielectric layer transparent.

The option of transparency processing material includes herein below：

Transparency processing material includes high molecular weight material, and it preferably will have as close possible to cellulose（It is in 592nm 1.55）Refractive index.

Transparency processing material can include synthetic polymer sill, such as acrylic resin, polyurethane and asphalt mixtures modified by epoxy resin Fat.In the case of epoxy resins, it may be necessary to single hardener/crosslinker material.

This method can also include the penetration depth that control transparency processing material is absorbed into object.It can control and wear Saturating depth builds the white point of model object with keep completing, and provides CMYK color as needed.
